For 1~ pumps with terminal box type (Fig. 4d):
• Speed change-over in the terminal box:
• Undo the terminal box cover screws, then remove the terminal box cover.
Adjust the selected speed by changing the position of the speed selector,
then correctly refit the terminal box cover.
For 3~ pumps with terminal box type (Fig. 4b and 4c):
The change-over switch in the terminal box can be set to one of a maximum of
two or three steps (depending on the terminal box type).
Undo the terminal box cover screws then remove the terminal box cover, pull off
the change-over switch (Fig. 4c) only with the pump switched off, then replace
it so that the symbol for the desired speed step in the terminal box is indicated
by the respective marking of the change-over plug.

through the viewing window.
NOTE: If on a twin-head pump both the individual pumps are in operation at the
same time, the selected speeds must be identical for both pumps.
